摘要： The present invention relates to the technical field of keeping freshness with electric field for refrigerators, and discloses a freshness-keeping refrigerator using electric field. The present invention includes a plurality of storage compartments and electric field releasing devices, and a voltage regulation device. The electric field releasing device is arranged in a separation layer of two adjacent storage compartments, or in a heat-insulating layer of a storage compartment, at a side close to the storage compartment, or in an edge foamed layer, at a side close to a storage compartment. The plurality of electric field releasing devices are in equipotential connection and are further connected in series to an output terminal of the voltage regulation device. The present invention regulates an electricity discharging strength of the electric field releasing device by the voltage regulation device. While it works, the electric field releasing device generates an electric field, which resonates with water molecules in a food so as to inhibit growth of a microbe, kill germs, decompose ethylene, inhibit activity of a food enzyme, and improve permeability of a cell membrane. Thus, losses of cellsap and umami constituents are greatly reduced, thereby achieving freshness-keeping of the food and a reasonable distribution of electric fields in a multi-compartment refrigerator. As a result, all compartments of the refrigerator are provided with uniform freshness-keeping, and the present invention has a wide application scope.
